This is a good question you brought up.

Honestly it depends on each marriage I guess. Does the internet porn take away from the marriage? Does it make the wife feel less as a woman? So on and so on...
My husband does not get on the computer for internet porn. However he does look at Playboy which doesn't bother me. In fact, I usually read a few issues and glance at the pictures before he does.
If he did decide to get online and check out the porn Id probably question it but I doubt Id get upset unless it got in the way of "us".
My husband is his own person as I am my own. We each have our own likes/dislikes. I feel each of us should be allowed to express or fill our own needs as we wish as long as it doesn't hurt our relationship or become disrespectful towards one another.
What works for one marriage may not work for another.
